ABSTRACT:
An injection and mixing device for the introduction of flocculant into aqueous material, such as sewage or sludge, prior to dewatering is disclosed. The device includes an angled housing and injection means for introducing the flocculant into the housing countercurrent to the incoming flow of aqueous material. The combination of the turbulence caused by the angled housing and the countercurrent injection evenly and rapidly disperses the flocculant within the aqueous material regardless of the material's solids content. A downstream sparger ring is also disclosed for use with high solids content material.
